The mod weigths c4.2 GB only now, when it is fully ready it will be a bomb! But nothing is lost... consider the idea of an "unofficial addon" for Shoker 2.1 and SWTC, that the player must install before...

Aight, nice!
One thing though.. (And this is just my opinion). Those bullet speeds?? you need to adjust those a great deal.
Example: In your mod the AKM have a muzzle velocity of 360 m/s. Its real world counterpart has one of around 700 m/s. The DE has a muzzle velocity of only 90 m/s in your mod (???), whilst its r/w counterpart has one of between 400 and 500 m/s.
Else I'm looking forward to your mod.
